Explanation:

 The Battle of Plassey was a decisive victory of the British East India Company over the Nawab of Bengal and his French allies on 23 June 1757. The battle consolidated the Company's presence in Bengal, which later expanded to cover much of India over the next hundred years.

The battle took place at Palashi (Anglicised version: Plassey) on the banks of the Hooghly River, about 150 kilometres (93 mi) north of Calcutta and south of Murshidabad, then capital of Bengal (now in Nadia district in West Bengal).
